Well actually, i like all of them.
the glasses guy because his nicknames are funny, and how he falls in love and has crazy illusions just like karin does.
Micchi because he is light-hearted and brings relief to "dramatic" moments
passifist cross dresser
and kazune + Karin's love hate relationship

i do not like the slow talking himeka-chan much, nor the eviler looking himeka-chan they are sorta annoying.
next season i doubt they will be as annoying
